Stuart Technologies — Modernization
Software Modernization without the rewrite gamble.
Move aging iOS, macOS, and web systems forward in controlled slices — modern frameworks, safer auth, and architectures you can keep shipping on.
When this is the right move
The app still makes money. The stack is the risk.
Full rewrites fail when the business cannot pause. We prefer strangler and vertical-slice migrations: replace the highest-risk surfaces first, keep data and customers moving, and retire legacy paths on purpose.
Typical triggers: UIKit/AppKit codebases that block hiring, Node or CMS stacks past their security window, auth that cannot grow, or “works on one machine” ops that scare the next hire.
Outcome is not a slide deck — it is a living system with fewer blockers for the next release.
Incremental cuts
Feature-by-feature migration plans with rollback points, not a multi-year “new system someday.”
Security & deps
Dependency hygiene, auth upgrades, and runtime paths that pass a serious review.
Keep shipping
Parallel tracks so product work continues while foundations improve.
Common tracks
Where modernization usually starts.
UIKit → SwiftUI
Screen-by-screen migration with shared models, Observation, and modern navigation.
Legacy web → Nuxt
SEO-safe SSR, typed APIs, and layouts that match how the marketing site already works.
Auth & sessions
Token rotation, safer cookies, and admin surfaces that do not share secrets in the clear.
Data layer
SwiftData / SQLite / API boundaries that stop the “god class” persistence layer.
Dependencies
Lockfile hygiene, security advisories, and drops of unmaintained packages.
Release process
TestFlight, staging, and deploy scripts that reduce heroics on release day.
